EDIT: IGNORE THIS - I got this wrong
The new "Smart System" components are not compatible with the older motor system used on the Gen 3 Rail 9.8

It is called “The Smart System” and unlike previous releases of...
I have a Rail 5 with same brakes as you. I have done 2,500km on them and they have always been completely silent. I have replaced two sets of pads on the back and one set on front as well as the rear rotor all with same parts as orignal (resin pads). I have had no problems with them.
100% agree, this is a bad idea and only likely to cause you trouble in the future, just do it properly.
Also you are missing the best part of being able to shift under full power
You can check compatibility here

Gen3 Levo is listed so it is compatible.

Says Hope have a new chainring that is compatible, I don't know if...
Hmm, if the Hope hub is correct then the SRAM derailleur is way out (about 1mm)
I don't think that is likely, I expect SRAM calibrate it in house to much less than that, each micro adjust is about 0.2mm so it should be accurate to that.
Fortunately the Hope hub measures wider than it should be...
I am running XO transmission on Trek Rail 5 with original e13 chainring which has a 52mm chainline, rather than the recommended 55mm
Neither the chain ring or the chainline are causing any problems as far as I can tell
Having said that I will order a SRAM T-Type chainring as soon as they are...
Great
The blue sleeve is a tool to aid installation of the locknut to avoid damage to the seal, it is not fitted to the bike.
I did an explainer video in post #1,591
Excellent Thank-you! First time I have seen the real seal.
This looks like a standard oil seal, which is basically what I have drawn in my CAD model, so I'm happy about that.
I can't make out the retaining band that you pointed out. The ring pointed to is just the outer part of the seal.
The...
Thanks, glad that was helpful
Yeh, the seal shouldn't be damaged by the 20 tooth tool since it only touches the robust back face of the seal.
EDITED:
I don't think the splines on the shaft are the main concern.
The purpose appears to be to get the seal safely over the lip where the shaft...
OK, Just for fun I've created an animation of the Locknut installation, showing the use of the installation sleeve, and showing the seal that I've been talking about.
Again this is from my CAD model so there could be inaccuracies.
If the seal doesn't look right please post a photo so I can...
I'd recommend getting one from Trek. It needs to be very smooth and it needs to be slightly tapered (conical) so that it slowly expands the seal to the right diameter by the time it gets to the shaft.
OK Great, It sounds like new deliveries have the seal installed in the locknut, plus they are supplying the sleeve that is used to ensure that the seal doesn't get damaged when installing the locknut.
I was getting the impression that the seal may not be installed on some bikes.
I'd suggest...
I don't see a seal in that lock nut. I see the oring but no seal to the spindle.
Trek says in the manual supplement that damage to the seal could allow water to damage the motor.
Presumably no seal would also allow water to damage the motor.
Has the seal been removed?
Has anyone else checked if...
